摘　　要：A novel carbazole photoinitiator 1-(6-o-chloro-benzoyl-9-ethyl-9H-carbazol-3yl)-ethane-1-one oxime O-ethyrate is synthesized from carbazole by N-alkylation,Friedel-Crafts acylation,oximation and esterification.The structure is characterized by 1HNMR,13CNMR,UV and IR.This paper discuss the catalyst,temperature and time of oximation and gain the optimum reaction conditions:CH3COOK is base,temperature is 70℃ and time is 6h.The yield is 89.1%.A novel carbazole photoinitiator 1-（6-o-chloro-benzoyl-9-ethyl-9H-carbazol-3yl）-ethane-1-one oxime O-ethyrate is synthesized from carbazole by N-alkylation, Friedel-Crafts acylation, oximation and esterification. The structure is characterized by ^1HNMR, ^13 CNMR, UV and IR. This paper discuss the catalyst, temperature and time of oximation and gain the optimum reaction conditions ： CH3 COOK is base, temperature is 70℃ and time is 6h. The yield is 89.1%.
